Oysters from the James displayed variations in Kepone residue levels related to water temperature and their spawning cycle. Oyster depuralion rates were related to temperature. In summer the "biological half. life" of Kepone in oysters was about one week, while during the winter about 40 days were required for residue levels to decline by 50 per cent. Residues in blue crabs varied as a function of sex, males having considerably higher residues than females. Fin fish levels from the James varied greatly, with residue levels being dependent on species and length of residence for migratory fishes .. Average Kepone residues …
